Elements hosted to link topography will be preserved when a revised link is reloaded.
When working with linked topography, hosted elements—including site components, plantings, spot annotations, subdivisions, and other similar elements—are preserved when the linked topography is reloaded.
Note: Slab edges will not be preserved.
If the geometry of the reloaded link has changed significantly, to the extent that the original host facets no longer appear on the geometry, the elements will not be re-hosted at their original positions. (Applies to face based elements).
For additional information, see Link Topography.
